To allY whom .it may concern:

Be it known that ISAAC F. MANNINd, citizen of the United States,residing at Ottawa, in the county of Lasalle and State of Illinois, hasinvented certain new and useful Improvements in Endless Conveyer Belts,of which the following is a s eciiication.

This invention re ates to improvements in that class ofendless 'conveyerbelts, having side flanges or guards which prevent material beinghandled escaping at the sides of the belt. The object of this inventionis to produce such a belt, available for use either to carry or elevateear or shelled corn and other farm produce, or'for conve ing orelevating coal, sand, gravel, or other ard substances which would tendto rapidly cut and destroy a belt of fabric `or leather.

In the accompanying drawings Figure 1 is a perspective view of a knownform of elevator frame for corn shellers, my improved belt being shownin position thereon. Fig. 2 is a perspective view of a section of myimproved belt on a large scale. Fig. 3 is a detail erspective of one ofthe belt shoes.

Hldretofore it has beenusual to employ in the construction of elevatorsandconveyers` for corn-shellers and the like, sprocket chains providedat intervalsv with flights, said conveyers being mounted to travel overthe I trough-like platform of the conveyor or elevator frame, and beingactuated b sprockets on rollers or drums journaled in t e elevator frameat opposite ends of the platform. One

'objection to this type of elevator has been/ that the friction of thechains and load-on the platform h s required excessive power foroperating t e elevator, and also it has been found that the materialconstituting the load to be elevated was liable to clog the sprocketchains or become lodged between them and the sprockets, thus occasioningdelay/if not damage. f

In canyin out my invention I prefer to employ a be t of iiexible webbingor belting, obtainable in desired sizes in the market, because lof theease with which it travels about its supporting rolls or drums and itsgreat strengt as comparedy to its weight, ut I dol not confine myself tothe use of said material. L

Referring to the drawings the belt proper A comprising an endless bandof belting isv provided upon one side with a plating consisting ofnarrow' shoes B of sheet metal bolts or rivets b the ends of -the shoesbeing bent outward atl-ight angles to form .guar

sections B at either end of each'shoe, and the shoes being arrangedlwith their edges closely adjacent or practically abutting so that theentire surface of the. belt is rotect.- ed by a sectional metal plating,t e bent ends of the shoes constituting a continuous sectional guard orflange at each edge of. the belt. -The several guard sections areextended at one edge b vto overlap the next adjacent section, and are ofsufliciently greater width at the outer end than adjacent tothe belt toinsure the continuit of the guard or flange 'at its outer edge W enpassln around the rolls onwhich itma be mounte The outer edges of theguar sections are beveled or sloped from a point b2 to insure an absenceof rojecting points asl the belt traverses a ro as shown m Fig. 3, andat the up er and lower ends of Fig. 1 the degree of s ope or bevel belof course determined by the diameter o the rolls on which the belt is`to be mounted, as will be readily understood.'

The belt is providedy at suitable intervals with fl hts CA consisting ofmetal plates bent at one ongitudinal and both end edges to form flangesc c c which are riveted respectively to the body of the shoe B and tothe guard sections B- at the ends thereof, as

shown. The main body of these flights is preferablynot at right anglesto the belt and lts supporting shoe, but inclined slightly in thedirection of the travel of the belt, and the outer edge C2 of each fliht is bent or stamped secured transversely to the belting by belt toincline still farther orward in the direction of travelof the belt,preferably terminating at the forward edges b of the extensions of theguard sections, ,as shown, thus alfording at intervalsthrou hout thelength f vof 'the belt recesses or poc ets which will carr fine materialeven though the opposite aps of the belt Ibe traveling in verticalplanes. j

. Conveyer or elevator frames or machines des' ned for use with aconveyer composed .f

of c ains and flights may be adapted'for use with my improved belt ,bysubstituting elongated pulleys or rolls for the sprocket wheels andshafts, and substitutin ,supporting orM bearing rolls for the plat .orm..`o`v`er which the cham conveyor travels. In `'constructing a frame formyv improved belt,

however, .the-broad side pieces of the carrier iframe are unnecessary asthe `side guards "or the anges of the belt fulfil their function ofpreventlng material from dropping from the sides of the belt.

As shown in Fig. 1, a frame Well adapted to my belt may consist of stoutside pieces 1 and endpieces 2, the ,journals of the rolls 3 on which thebelt travels being mounted in bearings 3a secured to the under sides ofthe side Hieces. The small supporting or bearing -ro said side pieces,the rectangular frame thus described having any transverse or diagonalbraces found' necessaryA to ive it the strength and rigidity required orthe Work to be performed.

The belt.may be actuated by extendin v the journal of one of the pulleys3 an mounting thereon a band-pulley crank or sprocket Wheel that it maybe driven from s 4 are journaled atv suitable distances apart inbearings 5, carried by' any suitable source of ower and I contemplatealso mounting a y-Wheel upon one of said shafts or journals to steadythe travel of the belt.

' What I claim as new is A conveyer belt consisting of an endlessflexible base, a carrier surface or plating comprising narrow metalshoes secured transversely on the base, and sectional guards or flangescarried by the shoes, each extended at 'one' ed e to overlap the nextad'acent guard, sai( guard sections being beve ed at.

the outer end. l

In testimony whereof I a'HiX my signature, in presence of two Witnesses.
